Imp is a small devious being who is a child in his dimension (7th to be exact) even though he is over one thousand years old. Imp is insanely powerful with poorly controlled abilities that range from turning New York City into ice cream to accidently ending reality. Imp had been having a affair with fellow teammate Deadly Nightshade, sometimes going out of control therefore endangering reality itself everytime he takes it under the covers.
Imp was taken by suprise and killed by Sucker when Mr. Rictus betrayed The Professor.
Imp can warp reality to whatever he pleases and has an array of powers, although he was asked to tone it down a notch after turning New York City into ice cream andin light of the fact that he can unmake reality. He is the one who rewrote history such that superheroes had never existed in the revised continuity.
